Some strange(perhaps deliberate) misremembering by Scanlon in his book. He talks about his '83 W meeting with Mac(a 75, 76, 76 loss) and says he was encouraged by the fact that he had set points in all 3 sets. He says that '3 points' was what he kept telling himself throughout the summer & in his USO rematch with Mac. I watched that match recently, & Scanlon only had one set point(which was in the 2nd set tiebreak)
The USO match was epic.
I have like a hundred Mac matches on tape. I would say half of all his tantrums were when he was leading. Weird how often fans today seem to forget this(when was his tantrum in his most famous loss at the French? when he was up 2 sets to love) He was always on edge in every match, no matter what the score. He could be up 1-0 in the first and completely lose it.
and having watched so many of his matches within recent years, I would say he was right a lot of the time in his arguments(at least say pre 1985). The umpires used at 1980 Wimbledon wouldn't be qualified to umpire USTA leagues today, they were woefully incompetent, unaware of some of the most basic rules("let's play a let" after Mac hits an ace that was called out. Mac explains its either an ace or a fault, and somehow he's the bad guy???) many players of the past just put up with their cluelessness, but Mac could not let it slide(Borg & Vilas and many of the good guys have talked about the 'amateurish' nature of officiating in the 70s)
